Recently some phones, especially phones from outside Namibia, connect to the router without internet access. Most phones of Namibians connect. We use the router as an access point connected by cat6 cable to the main router which is a FritzBox 7590. Our local network provides wifi to guests at our guest house. Many guests are kind and patient. Some are not!. My android phone and my laptop access the internet and browse or email without issue via the TL-WA801N
I am not an IT technician but I understand a few things. I am baffled.
